Actually I'm new in Flutter and Get!
I'm really confused by GetPage, onGenerateRoute, Navigator and ...
Tried many approach of this concept but can't get it done.

Nested Navigation in Flutter is a little tedious. If you are new to all the ecosystem, you should definitely make some research first. First check how Flutter Navigation works by itself, and then try to accomplish the same with GetX. There's a ton of material in Medium and YouTube about it...

I'm working on this for a week or so.
Watched almost all YouTube tuts about GetX and read every docs and contents about navigation in Flutter and GetX!
But its really confusing or I'm really stupid :D
Thanks for your time 👍
